Answer 1

You can do one of these

public function collection()
{
   // Carbon::today() === today()
   return CosQueue::whereDate('created_at', Carbon::today())->get(array('full_name', 'job_title','meeting_with','subject','date'));
}

Also, you can do

public function collection()
{
   return CosQueue::whereDate('created_at', date('Y-m-d'))->get(array('full_name', 'job_title','meeting_with','subject','date')); 
}
